(Κυδίας).
1. An Athenian orator, a contemporary of Demosthenes, of whom Aristotle (Aristot. Rh. 2.6.24) mentions an oration περί τῆς Σάμου κλμρουχίας, which Ruhnken refers to the Athenian colony which was sent to Samos in B. C. 352 (Dionys. Deinarch. p. 118), so that the oration of Cydias would have been delivered in that year. (Ruhnken, Hist. Crit. Orat. Graec. p. Ixxiv.)
